NApoleon decisively defeated the Prussians in a fighting campaign that culminated at the Battle of Jena-Auerstedt on 14 October 1806. FRench forces under Napoleon occupied Prussia, pursuing the remnants of the shattered Prussian Army, and captured Berlin on October 25 1806, then moved all the way to East Prussia, Poland and the Russian frontier, where they fought an inconclusive battle against the Russians at Eylau in February 1807. NApoleon''s advance on the Russian frontier was briefly checked. RUssian forces were crushed by Napoleon''s army at Friedland on June 14, 1807, and three days later Russia asked for a truce. BY the Treaties of Tilsit in July 1807, France made peace with Russia and received half of Prussia''s territory, Jerome Bonaparte''s Kingdom of Westphalia, and the new Duchy of Warsaw. NApoleon was now master of all of western and central continental Europe, except for Spain, Portugal, Austria and several smaller countries.
